[OpenIndiana-discuss] OpenIndiana/ZFS mail server HA config

[Hans J. Albertsson]

I noticed AVS: This is too recent for me to have had any chance of 
learning about it while at Sun.
Could this be used for remote mirroring between two standard Supermicro 
X8STi-LN4 based microserver
using two ordinary SATA disks each?

And can that motherboard be expected to work OK with OI151a?
